- License info
Before using our SDK make sure you have installed CompreFace and Nodejs on your machine.
- CompreFace (See below compatibility matrix)
- Nodejs (Version 10+)
CompreFace JS SDK version | CompreFace 0.4.x | CompreFace 0.5.x | CompreFace 0.6.x |
---|---|---|---|
0.4.1 | ✔ | ✘ | ✘ |
0.5.x | ✘ | ✔ | 🟡 |
0.6.x | ✘ | 🟡 | ✔ |
Explanation:
- ✔ SDK supports all functionality from CompreFace.
- 🟡 SDK works with this CompreFace version. In case if CompreFace version is newer - SDK won't support new features of CompreFace. In case if CompreFace version is older - new SDK features will fail.
- ✘ There are major backward compatibility issues. It is not recommended to use these versions together
To add CompreFace JS SDK to your project, run the following command in the project folder:
npm i @exadel/compreface-js-sdk
To start using JavaScript SDK you need to import CompreFace
object from 'compreface-js-sdk' dependency.
Then you need to init it with url
and port
. By default, if you run CompreFace on your local machine, it's http://localhost
and 8000
respectively.
You can pass optional options
object when creating CompreFace to set default parameters, see reference for more information.
After you initialized CompreFace
object you need to init the service object with the api key
of your face service. You can use this service object to recognize faces.
However, before recognizing you need first to add faces into the face collection. To do this, get the face collection object from the service object.
import { CompreFace } from 'compreface-js-sdk';
let api_key = "your_key";
let url = "http://localhost";
let port = 8000;
let compreFace = new CompreFace(url, port); // set CompreFace url and port
let recognitionService = compreFace.initFaceRecognitionService(api_key); // initialize service
let faceCollection = recognitionService.getFaceCollection(); // use face collection to fill it with known faces
let subjects = recognitionService.getSubjects(); // use subjects object to work with subjects directely
Here is JavaScript code example that shows how to add an image to your face collection from your file system:
let path_to_image = "../images/boy.jpg";
let name = encodeURIComponent('Tom');
faceCollection.add(path_to_image, name)
.then(response => {
// your code
})
.catch(error => {
console.log(`Oops! There is problem in uploading image ${error}`)
})
This code snippet shows how to recognize unknown face:
let path_to_image = "../images/team.jpg";
recognitionService.recognize(path_to_image)
.then(response => {
console.log(JSON.stringify(response));
})
.catch(error => {
console.log(`Oops! There is problem with recognizing image ${error}`)
})
NOTE: We provide 3 ways of uploading image to our SDK. They are url, blob and relative path (from local machine).
Enviroments | from URL | with Blob format | from local machine |

Global CompreFace Object is used for initializing connection to CompreFace and setting default values for options. Default values will be used in every service method if applicable. If the option’s value is set in the global object and passed as a function argument then the function argument value will be used.
Constructor:
new CompreFace(server, port, options)
Argument | Type | Required | Notes |
---|---|---|---|
url | string | required | URL with protocol where CompreFace is located. E.g. http://localhost |
port | string | required | CompreFace port. E.g. 8000 |
options | object | optional | Default values for face recognition services |
Possible options:
Option | Type | Notes |
---|---|---|
det_prob_threshold | string | minimum required confidence that a recognized face is actually a face. Value is between 0.0 and 1.0 |
limit | integer | maximum number of faces on the image to be recognized. It recognizes the biggest faces first. Value of 0 represents no limit. Default value: 0 |
prediction_count | integer | maximum number of subject predictions per face. It returns the most similar subjects. Default value: 1 |
face_plugins | string | comma-separated slugs of face plugins. If empty, no additional information is returned. Learn more |
status | boolean | if true includes system information like execution_time and plugin_version fields. Default value is false |

Face recognition service is used for face identification. This means that you first need to upload known faces to face collection and then recognize unknown faces among them. When you upload an unknown face, the service returns the most similar faces to it. Also, face recognition service supports verify endpoint to check if this person from face collection is the correct one. For more information, see CompreFace page.
